Application filed May 22, 1925. Serial No. 32,106.

The invention relates to containers, and more particularly the method and means for securing the head to the siding for the cover or main body of the container.

5 The object of the inventionis to provide a construction in which the head of the container fits within the siding and is clamped thereto by a reinforcing band of sheet metal and a metal ring cooperating W with said band.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a view, partly in elevation and partly in section, of a container embodying the invention;

Fig. 2 is a detail sectional and perspective view showing the container parts in 29 position for attaching the ,head or closure;

Fig. 3 is a detail sectional view showing the apparatus with container parts in position for attaching the closure. r

The siding 4 for the container is fibre 25 tubing, either of pressed pulp'or a number of wrappings of paper or fibre sheets, and is generally in the form of cylindrical or conical tubing. This siding preferably is shoul-' dered, as at 5, to receive the edge of a lamiso nated'fibre head 6 having one or more of the laminations T extending beyond the others to form a dished head which fits within the siding.

A reinforcing metal ring 8 cooperates at with a reinforcing metal sheathing or band 9 to tightly clamp the head and siding toether and form a strongly reinforced edge. uring the process of manufacture the ring 8 is placed within the dished head, and the to band 9, with its upper edge 10 curved slightly inwardly, is placed around the siding, as shown in Fig. 2, and-these parts are held between an inner anvil or chuck 11, an outer chuck 12 and a plunger 13. Associated at with the plunger 13 is an annular edge-forming part or member 14, having a concave edge 15, said member 14; working between the chuck 12 and the plunger 13 and serving,

on its downward pressing stroke, to curl the to free edge 16 of the band 9 about the ring 8,

and at the same time curl the edge 17 of theflanged portion of the dished head, as well band not only strengthens the edge of the container adjacent the band, but also prowrites an elficient grip for the sheathing curled about it and thus assists the band in firmly holding the siding and head in place.

While containers of this general type are usually made cylindrical or conical in shape, they may be of polygonal shape, and l[ therefore desire it to be understood that the terms band or ring include broadly such metal sheathing and reinforcing members as would be used on polygonal shaped containers in the same way that the band 9 and ring 8 here shown are used on cylindrical or conical containers.

'll desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are specified in the claims.

What ll claim as my invention is:

' 1. In a container, the combination with the siding. of ahead fitting within said siding, a metal sheathing, and a metal ring cooperating with said sheathing and engaged thereby to clamp said head to said siding.-

2. In a container, the combination with the siding, of a head fitting within said siding, a metal sheathing having a clamping edge, and a metal member engagin said head and engaged by the clamplng e ge of said sheathing to clamp said head to said siding.

3. In a container, the combination of a siding, a dished head fitting within'said siding, a metal sheathing fitting over said siding, a metal'ring fitting within the annular portion of said head and cooperating with said sheathing to clamp said head to said siding.

4. In a container, the combination of siding having a shouldered end portion, a head fitting within said siding and abutting said shoulder, a metal sheathing fitting over said siding, and a metal ring engaging the head and engaged by said sheathing to clamp said head to said siding.

5. In a container, the combination'of sid- 5 ing having a head-receiving shoulder, a dished head mounted Within said siding and abutting said shoulder, a metal ring disposed adjacent the annular portion of said dished head, and a metal sheathing fitting over said siding and cooperating with said ring to clamp said siding and head between it and the ring and to clamp said head between said ring and shoulder.

In testimony whereof, I aflix my signature.

EDWIN F. HULBERT.
